Answer 1

Answer:

$\huge\colorbox{pink}{Question ↓↓}$

The structure of Parenchyma, Collenchyma and sclerenchyma.

[ the first picture is of Parenchyma! ]

[ the second picture is of Collenchyma ]

[ The third picture is of Sclerenchyma ]

$\huge\colorbox{pink}{∆ Functions ∆}$

Parenchyma:-

∆ It consists of relatively unspecialised cells with thin cell walls.

∆ They are living cells.

∆ They are usually loosely arranged, thus large spaces between cells are found in this tissue.

∆ The tissue generally stores food.

Collenchyma:-

∆ It provides flexibility in plants.

∆ It allows bending of various parts of a plant like tendrils and stems of climbers without breaking.

∆ It also provides mechanical support.

∆ The cells of this tissue are living, elongated and irregularly thickened at the corners.

∆ There is very intercellular space.

Sclerenchyma:-

∆ It makes the plant hard and stiff.

[Eg. = Coconut.]

∆ The cells of this tissue are dead.

∆ They are long and narrow as the walls thickened due to lignin.

∆ Often these walls are so thick that there is no internal space between them.

∆ This tissue is present is stems, around vascular bundles, in the veins of leaves and in the hard covering of seeds and nuts.

∆ It provides strength to the plant parts.
